8-9 THE UNITS CAN GIVE OFF ODOURS
•
The unit can absorb the smell of rooms, furni-
ture, cigarettes, etc., and then emit it again.
8-10 THE OUTDOOR UNIT FAN DOES NOT
SPIN
•
During operation.
The speed of the fan is controlled in order to opti-
mize product operation.
8-11 THE DISPLAY SHOWS
“
”
•
This is the case immediately after the main
power supply switch is turned on and means
that the remote controller is in normal condi-
tion. This continues for one minute.
8-12 THE COMPRESSOR IN THE OUT-
DOOR UNIT DOES NOT STOP AFTER
A SHORT HEATING OPERATION

This is to prevent oil and refrigerant from
remaining in the compressor. The unit will
stop after 5 to 10 minutes.
8-13 THE INSIDE OF AN OUTDOOR UNIT IS
WARM EVEN WHEN THE UNIT HAS
STOPPED
•
This is because the crankcase heater is warm-
ing the compressor so that the compressor
can start smoothly.
